Mitotic Division in Cancer Cells A key characteristic of cancer cells is that they are no longer constrained by the standard cell
cycle controls that normally coordinate cell division activity. Consequently, the timing of mitosis
in cancer cells is altered. You may have heard of cancer cells being "runaway" which have no
controls on their rate of reproduction. It is this characteristic that allows some cancer cells to
grow and spread quite rapidly. In this activity, you will analyze data to determine the difference
in timing of mitosis between normal stomach cells and cancerous stomach cells of the chicken.
